CHARLES S. PIPPIN, OF COALDALE, WEST VIRGINIA.

ICE-CREAM-SHIPPING CAN.

Application filed March 30, 1923. .Serial No. 628,808.

T 0 all whom t may concern.:

Be it known that I, CHARLES S. PIPPIN, a citizen of the United States, residing at Coaldale, in the county of Mercer' and State of 1rNest Virginia, have invented certain new and useful Improvements in an Ice- Cream-Shipping Can, of which the following is a specification.

rIhis invention relates to cold storage shipping can and more particularly to an improved receptacle or can in which ice cream may be frozen and shipped and maintained under a low temperature while the receptacle is in transit.

Another object of the invention is to provide a can or receptacle of this character which will include a coil of pipe adapted to be connected in the pipe line of a refrigerating` system so that a number of the cans or receptacles may be connected in series or individually to the refrigerating 'system while the freezing process is carried on.

A further object of the invention is to provide a receptacle of this character which will be constructed so that the interior compartment will retain the cold for a considerable length of time so that the contents of the container will be maintained at a low temperature while the receptacle is being shipped.

Other objects will appear upon consideration of the following detail description and accompanying drawing in which:

Figure 1 is a longitudinal section through the device constructed in accordance with my invention.

Figure 2 is a top plan view thereof, and

Figure 3 is a cross section taken on the lines 3 3 of Figure 1.

Referring 'to the drawing by numerals the outer casing 1 is of cylindrical form and has a bottom wall 2 and an open top 3 to which is attached a tight cover L having spring latches 5 carried by the casing 1 and adapted to be connected to suitable clip members on the cover whereby the latter will be held in tight engagement with the top of the casing when the cover is in applied position. Obviously the casing may be of any size according to the quantity of material to be placed within the receptacle.

Arranged within the outer casing is the inner receptacle 5 which also is of -cylindrical form and of a diameter less than the interior diameter of the outer casing so that a space 6 is provided between the outer and inner containers.v Spacing members 7 are arranged in the space 6 to maintain the inner receptacle in proper spaced relation and a coil of pipe 8 is coiled around the outside of the inner receptacle 5, the coil extending' from the upper to thelower end .of the inner receptacle as shown. The ends vof the coil of pipe S are extended through the wall of thev outer casing to provide the connecting ends 9 and 10 which may be coupled to the system of piping used in the refrigerating system.

The top of the inner receptacle is provided with a tightly fitting removable cover 11 and the bottom wall of the inner receptacle is raised as indicated at 12 so that it will be above the bottom of the outer casing thus providing a bottom air space 13. The cover 11 is depressed as illustrated so that an upper air space 14: is` provided between the cover l1 and the cover of the outer casing so in this manner an air space is provided entirely around the inner receptacle through which a free circulation of air may be had.

In use7 the ice cream or other commodity will be placed within the inner receptacle and the cover 11 applied in position. coil of pipe 8 is thenaconnected in the refrigerating system and the temperature of the air in the air space will be gradually reduced until-the contents of the inner receptacle is frozen and the pipes may then be disconnected from the refrigerating system and receptacle utilized as a shipping container.

Minor changes may be made in the details of construction without departing from the spirit of the invention or the scope of the claims hereunto appended.

Claims:l

1. A shipping receptacle of the character described comprising an outer casing, a removable cover or the casing, latch spring carried by the outer casing` and engageable with the cover to maintain the latter in air llO tom of the outer easing and the inner receptacle, and a coil of pipe surrounding` the inner receptacle and having its ends extended through the Walls of the outer casing.

2. A device of the character described Comprising an outer easing of cylindrical form having an open top` provided With an air tight removable cover, an inner receptacle of a. diameter less than the diameter of said outer easing Whereb7 an annular space isprovided between the inner receptacle and the outer easing, means interposed between the inner receptacle and the outer casing to maintain the inner receptacle in spaced relation from the Wall of the outer Casing, the bottom of the inner receptacle being elevated to provide a bottom air space in communie-ation With the said annular air space7 a. removable cover for the said inner receptacle, the Said cover being depressed to provide a top` space between the receptacle cover and the cover for the Said outer easing, said top space being in Communication With the said annular air space, a coil of pipe extending around the inner receptacle from the top to the bottom thereol", the opposite terminals of the said eoil of pipe being extended through the Wall oi the outer casing. at diametrieally opposite points.

In testimony whereof, I have alixed my signature in the presence of two Witnesses.
